I recently got this amazing profile done by Dasani Decoded and I love it! I've been meaning to change my profile, and this was perfect.

It was fun brainstorming some cool Math equations and expressions to include in the picture. What's your favorite Math equation or expression?

¡Recientemente Dasani Decoded me dibujó este increíble perfil y me encantó! Tenía la intención de cambiar mi perfil, y esto fue perfecto.

Fue divertido hacer una lluvia de ideas sobre algunas ecuaciones y expresiones matemáticas geniales para incluir en la imagen. ¿Cuál es tu ecuación o expresión matemática favorita?

This is my first weekend that doesn't feel like a weekend since I'm finally done with undergrad! 2 days ago, I presented my last assignment as an undergrad: my Math senior capstone titled "Skeletons of Generic Polynomials and Rational Maps". Even though I worked with my advisor, Dr. Joel Langer, for a year, I was still hesitating about presenting my work as a capstone, but I'm so glad I gave it a try =)

Have you ever gotten 16 free Math books? On the last Math conference I went to, they were giving out free Math books to students. At the beginning I just took a few, but at the end of the conference, after noticing there were still many books available, I took many more. I have always wanted to build a shelf of Math books, so this is a great start =) what's your favorite Math book?
